A posteriori error estimates in a finite element VMS-based reduced order model for the incompressible Navier-Stokes equations
Codina, Ramon; Reyes, Ricardo; Baiges Aznar, Joan (2021-03)
Article
Accés obertIn this paper we present an a posteriori error estimate for a reduced order model (ROM) for the incompressible Navier-Stokes equations that is based on the fact that the full order model is a finite element (FE) approximation. ... -
Element boundary terms in reduced order models for flow problems: domain decomposition and adaptive coarse mesh hyper-reduction
Reyes, Ricardo; Codina, Ramon (2020-08)
Article
Accés obertIn this paper we present a finite-element based reduced order model and, in particular, we consider two aspects related to the introduction of inter-element boundary terms in the formulation. The first is a domain decomposition ... -
Projection-based reduced order models for flow problems: a variational multiscale approach
Reyes, Ricardo; Codina, Ramon (2020-05)
Article
Accés obertIn this paper we present a Variational Multi-Scale stabilized formulation for a general projection-based Reduced Order Model. In the stabilized formulation we address techniques already analysed in Variational Multi-Scale-Finite ... -
Reduced order models for thermally coupled low Mach flows
Reyes, Ricardo; Codina, Ramon; Baiges Aznar, Joan; Idelsohn Barg, Sergio Rodolfo (Springer, 2018-12)
Article
Accés obertIn this paper we present a collection of techniques used to formulate a projection-based reduced order model (ROM) for zero Mach limit thermally coupled Navier–Stokes equations. The formulation derives from a standard ... -
Stabilized reduced order models for low speed flows
Reyes, Ricardo (Universitat Politècnica de Catalunya, 2020-03-23)
Tesi
Accés obertThis thesis presents the a stabilized projection-based Reduced Order Model (ROM) formulation in low speed fluid flows using a Variational Multi-Scale (VMS) approach. To develop this formulation we use a Finite Element (FE) ...
